Title: Improvements in and relating to the disinfection of cereals, fruit, foodstuffs, textiles and the like
IPC: A23B9/18
Filed: 1930-05-16
Abstract: 357,127. Disinfecting by fumigation. CABRERA, R. M., 524, Florida Street, Buenos Aires. May 16; 1930, No. 15133. [Classes 49 and 81 (i).] Cereals, fruit, foodstuffs, textiles, &c., are disinfected by treatment with the vapour of carbondisulphide carried by a gas such as air which is saturated with the vapour by contact with liquid carbon disulphide and passed over the materials to be disinfected in a closed gastight circuit. A suitable apparatus comprises a vessel 1 for the materials to be treated having a door 5, an inlet 2 and outlet 8 for the vapour saturated gas and a discharge valve 14. The gas current is circulated by a pump 3 through a vessel 6 containing liquid carbon disulphide 10 and traps 11, 12, the chamber 1 and thence back through a pipe 9. A simple bottle containing carbon disulphide and material for trapping entrained liquid may be substituted for the vessel 6.

Title: Improvements in liquid level gauges
Inventor: NEISSE GERARD
IPC: G01F23/66
Filed: 1963-04-17
Abstract: 1,021,686. Liquid level indicators. EUROPEAN ATOMIC ENERGY COMMUNITY (EURATOM). April 17, 1963 [April 17, 1962], No. 15150/63. Heading G1H. A liquid level gauge in which a stream of gas from a supply conduit 1 issues from a nozzle 2 on to an impingement surface 6 which moves towards and away from the nozzle 2 with rise and fall of the liquid, the surface 6 as it approaches the nozzle causing an increasing back pressure in the conduit 1, the surface 6 being constituted by a feeler 8 operating in a discharge passage 13 downstream of the nozzle 2. The feeler 8 is in the form of a vertically reciprocable piston 12 resting directly on a float 5 on the liquid surface. The float is loosely held in place on the device by hooks 10, so that it is allowed a limited movement within the working range of the device. When the piston 12 is in its lowermost position i.e. resting on shoulders 14, it uncovers the inlet and outlet of an auxiliary conduit 15 to which gas is also supplied. The complete device,with the float 5, is mounted on a nut which is reciprocable on a rotary vertical screw threaded spindle driven by a hydraulic motor (Fig. 2, not shown). The back pressures in the conduits 1 and 15 are fed to a pressure operated relay circuit described in the Specification which controls rotation of the motor corresponding to upward or downward movement of the device. In operation with the device at a datum position above the liquid level to be measured, the motor is fed with a signal causing it to lower the device at maximum speed. When the float 5 contacts the liquid surface the piston 12 starts to rise causing an increase in back pressure in the conduit 15. This slows down the motor and subsequently the gas flow from the nozzle 2 is affected by the approach of the surface 6 causing increase of pressure in the conduit 4. Eventually the downward movement of the device is stopped, the level of the liquid being determined from the number of turns made by the screw-threaded rod. If the liquid surface subsequently rises or falls, the device will react accordingly to adjust itself to the new level.

Patent GB-467559-A (GB)
Title: Process of removing water from aqueous aliphatic acids
IPC: C07C51/46
Filed: 1935-09-12
Abstract: <PICT:0467559/IV/1> Lower aliphatic acids (other than formic acid) are concentrated by azeotropic distillation with a mixture of an alcohol and an ester, the aqueous acid or mixture of acids being fed in to the rectifying apparatus so far below the point at which the entraining agent is admitted that esterification is avoided, and the water is drawn off as a ternary mixture at the top.  Some hydrolysis of the ester may occur, and this may be counterbalanced by causing a corresponding esterification in a separate vessel or by returning a part of the entraining agent to a point in the system where the water present is sufficiently low.  Alcohol may be fed in at such a point to make up for losses of entraining agent.  The entraining agent may be propyl alcohol and acetate, n- or iso-butyl alcohol and acetate or amyl alcohol and acetate. The process may be carried out in the apparatus shown in Specification 383,148 and more than two columns may be employed. In the apparatus shown in the Figure, aqueous acetic acid is fed from a supply tank 38 to a column 41 which receives at the top a mixture of normal propyl acetate and propyl alcohol, and has a heating-vessel 44 at the bottom.  The ternary mixture escapes by a pipe 46 to a condenser 47, and the condensate separates into two layers in a vessel 49, from which the entrainer layer is returned to the top of the column 41, a part being byepassed to enter the column at a lower point 81 to cause the necessary esterification to maintain the composition of the entrainer.  The partially concentrated acid is led from the vessel 44 to a column 55 where a further concentration is effected.  Additional entraining agent may be added from a tank 90 to the top of the column 55, and the entrainer layer from the separating vessel 49<1> may be returned to the top of columns 41, 55 or a part may be byepassed to enter the column 41 at a lower part by a pipe 80 for esterification as described above.  Specification 327,444, [Class 2 (iii)], also is referred to.

Abstract: 1,136,194. Shielded containers for radioactive material. E. R. SQUIBB & SONS Inc. 4 April, 1967 [6 April, 1966], No. 15334/67. Heading B4Q. [Also in Division G6] A sterile column 3 containing radioactivity for medical use is housed in an opening 4 in a shielding container I closed by a shielding lid 2. The shielding material may be lead, a lead-antimony alloy iron, or a lead salt such as lead carbonate or lead sulphide embedded in plastic. Access to the column 3 is obtained by removing shielding plugs 8, 9 situated, respectively, in the base of the container 1 and in the lid 2. The column 3 is of glass or transparent plastic material and is closed by rubber stoppers 15, 16 pierceable by a hypodermic needle. A breather tube 19 connects the space in the lower end of the column to atmosphere and above the tube is a funnellike partition 22 supporting a perforated disc 24 of fritted glass. A filter pad 25 resting on the disc 24 supports a granulation 26 of a radioactivity - containing alumina. In use, radioactivity is introduced into the granulation 26 by piercing the stopper 15 with a hollow needle connected to a reservoir containing an aqueous solution of radioactive Mo<SP>99</SP> ammonium molybdate. Excess molybdenum and water are removed through a drainage needle piercing the stopper 16. To extract the radioactivity the column is eluted by injecting a non-pyrogenic isotonic saline solution through the stopper 15 by means of a hypodermic syringe, the eluate containing the radioactive material, i.e. the 99m isotope of technetium, collecting at the bottom of the column. When the eluate is to be used, it is removed by piercing the stopper 16 with a hypodermic needle. In a modification (Figs. 4, 5, not shown), there is no empty space at the lower end of the column and the eluate is removed whilst the column is being eluted.
